CLOVER-HULLER.

SPECIFICATION forming part of Letters Patent No. 331,646, dated December1, 1885.

Application filed July .24, 1885. Serial No. 172,545.

.To all whom it iii/ray concern:

Be it known that I, ABRAHAM MILLER, a citizen of the United States,residing at Newark, in the county of Licking and State of Ohio, haveinvented certain new and useful Improvements in Clover-Hullers, of whichthe following is a specification, reference being bad therein to theaccompanying drawings.

This invention relates to clover-hullers; and the novelty consists inthe construction, arrangement, and adaptation of parts for specificpurposes, as will be more fully hereinafter set forth, and specificallypointed out in the claims. It is designed as an improvement upon thatclass of machines similar to those patented to myself, No. 188,064, ofMarch 6, 1877, and to Jones and Miller, No. 44,431, September 27, 1864.It relates more particularly to the lower cylinder and concave.

In the accompanying drawings, which form a part of this specification,Figure l is a section taken along the longitude of the machine. Fig. 2is a similar view with the tool-box displaced. Fig. 3 is a face View ofthe lower concave. Fig. 4 is a detail view showing the peculiar meansfor detachably locking the Fig. 5 isa detail section of one of theconcave heads, and Figs. 6 and 7 are sectional views on the lines y yand z 2, respectively, of Fig. 5.

Referring to the drawings, A designates the frame of a clover-huller ofthe class described, and C6 the rear, and a the front, thereof.

B designates one of the heads of the concave, having its outer flange,I), cut away, as seen at b. The inner flanges, b, serve as abutments forthe staves, and the heads are beveled outward from the inner flanges topermit the easy removal of staves from the heads.

0 designates the upper staves, which are held in place by the segmentalflangesb and b 0' are the lower similar staves, and O the staves of theremovable section. The lower of the staves O and the upper of the stavesC have peculiar features, and I will designate them by the marks C and Crespectively.

D represents cleats or plates having handles d and end lugs, d. To thesecleats D, of which there are preferably two, are bolted or other- (Nomodel.)

wise secured the staves 0 which form the rigid detachable panel. Thelugs d operate under recesses 6, formed in the lower surfaces of turningbuttons E, arranged near the ends of the staves C and 0*, for thepurpose of holding the panel in position. If desired, the lower set ofbuttons may be rigidly secured to the staves C, the upper set onlyhaving sliding motion. \Vhen this panel is removed, the staves O O G Cmay bepassed bodily through the opening thus made and pushed under theflanges b into their proper places, their location and arrangement beingreadily fixed to have the stationary and movable rubbers agree. ThestaveG has a longitudinalgroove, through which the tie-rod 0 passes, andthis tie-rod passing through holes or slots b in the heads, in additionto the inner and outer flanges, holds this stave properlyin place. I canuse a joint bolt or screw at each end of this stave O in place of thetie-rod, but I prefer the rod. The upper and lower staves being properlylocated, there is left in the curve of the concaveaspace equal to thearea of the movable panel formed by the staves O and this panel beingput in place is securely locked by the buttons E to staves C and C. Bythis construction not only are the staves readily and quickly put inproper place with regard to the proper juxtaposition, when in action, ofthe stationary and movable rubbers, but in case of the breaking of anyof the rubbers, or for any other cause, the cylinder is readilyaccessible. In order to have ready access to the concave thus formed, Iprovide an open space in the rear of the machine, which is closed by theremovabletool-box G when said tool-box is in the position shown in Fig.1.

Secured to the end posts, c, or to a board which may be secured to suchposts, are looking-lugs F. The back part of the tool-box is perforatedto receive these lugs, and to the inner surface of the tool-box aresecured pivoted plates H, having guide-slots h which receive the bolts7L, and open slots 7L2, which re ceive and engage the lugs F, athumbscrew, h serving to secure plates H in a locked position.

The slots h and open slots h are formed with a curve describing the arcof a circle having the pivot for a center, and the tool-boxv may bereadily removed by the obvious manipulation of these parts to affordaccess to the concave. These features of construction are of importancein this class of machines when inspection or repair of the working partsis necessary.

In details of construction modifications may be made within wide limitswithout departing from the principle or sacrificing the advantages of myinvention, the essential features of which will be readily understoodfrom the foregoing descriptiomtaken in connection with the drawings.

What I claim as new is- 1. In a clover-huller, the concave heads havinga portion of their outer flanges cut away to allow the insertion of theupper and lower staves, combined witharemovable panel having stavescorresponding to such cutaway portion, as set forth.

Q2. The heads B, having inner flanges, b and outer flanges, I), cut awayat b, the said sides being beveled from the flange b outward beyond thecutaway portion, as set forth.

3. In a concave of a clover-hullcr, the heads B, having slots I),combined with a stave, 0", having a longitudinal slot and a tie-rod, c,a removable panel, and one or more separately removable staves, as andfor the purpose specified.

4. In a clover-huller, a concave consisting of upper and lower staves,two or more staves formed into a separate removable panel, and means forsecuring the said removable panel in place, as set forth.

'5. In a clover-huller, the combination of upper andlowerstaves with twoor more staves formed into a panel, plates D, having projections (1, andbuttons, as E, having recesses e, as set forth.

6. In a clover-huller, the combination, with the upper and lower stavesof the concave, of a removable panel consisting of a number of staves,metal plates secured to said staves and having handles, and buttons, asE, for locking said panel in place, as specified.

7. In a lower concave, the combination of the heads or sides B withcut-away flanges, the stavcs O C, locking tie-rod c, removable panel andsliding buttons arranged on said staves C O for locking said panel inplace, as set forth.

8. The concave described, comprising heads or sides B, with cutawayflanges b b, the staves C (3, held by the flanges b b, the removablepanel formed by the staves C and plates D, with lugs d, and the buttonsE, with recesses e, as set forth.

9. The combination, with the lower cylinder and concave and the casingof a cloverhuller having an open space opposite such concave, of aremovable tool-box adapted, when in position, to cover said space,as'set forth.

10. The combination, with the frame having lugs or pins, as F, of aremovable tool-box, G, having slotted plates H, as set forth.

11. The combination, with the removable tool-box G and lugs F, ofpivoted plates H, having curved slots 7L2, and set-bolts h, as and forthe purpose set forth. I

'12. In a clover-huller, the combination,with the upper and lower stavesof the concave, of a removable panel, plates secured to said panel andhaving handles, and means for securing said removable panel in place, asand for the purpose set forth.

13. In a clover-huller, the combin ation,with two or moreseparately-removable staves,'of a removable panel formed of two or morestaves rigidly secured together, and means for securing said removablepanel in place, as set forth.

In testimony whereof I affix my signature in presence of two Witnesses.

ABRAHAM MILLER.
